Pulsarguard 2001

Functional Description

The Pulsarguard 2001 is an ultrasonic sensor that has been designed primarily
for use by the oil and gas industry in conjuction with the Pulsar SandAlert
sand monitoring system.

This Sand monitoring sensor is more immune than previous sensors to the
noise that can be received from high flowing wells.

The unit can be used as a direct replacement for the previous sensor (still
available and called PULSAR guard 2011).

Installation

Sensor Positioning

Sensor Positioning

The acoustic sensor detects the high frequency sound generated by the
impacts of sand and other solid particles e.g. proppant on the inside of the
pipe wall. Therefore, the best results will be obtained if the sensor is
positioned on or just after a bend (within two pipe diameters of the bend),
or fixed restriction to the flow. See Figure above.

Do not position the sensor in close proximity to a choke, or other variable
restriction, since changes in the choke position may affect the SIR
readings. It may be necessary to experiment with the sensor position to
obtain the best results.

Details for use of the 11mm banding

This is an acoustic sensor and the coupling between the pipe and the
sensor is critical, make sure the pipe is clean and smooth (use sandpaper if
necessary to clear the surface of paint or rust).

Power Supply Requirements

This unit is a hazardous area product and certified to be used
in Zone 0, therefore it must be supplied via a suitable 28V
safety barrier, either zener or galvanic. Suitable barriers are
contained with the SandAlert portable and the SandAlert lite.

Wiring Detail

Pulsar Process Measurement Ltd. PG-2001-4 Page Page

Connections are as follows: Cable screen should be earthed at the barrier
end (SCREEN). The Power terminal should be supplied with 24V from a
28V barrier (POWER+). The signal and power returns (grounds) connect to
the 0V terminal. The signal terminal should connect (SIGNAL+) via a
barrier to the processing unit. Ensure that the lid is refitted and all screws
are tightened to ensure a good seal.
